To A LL 'WHoM IT MAY coNoERN:

vBe it known lthat I, ALMERoN BRISTOL, of Constantine, St.- Josephs county,State of Michigan, have invented certain new and useful Improvements in Fly-Traps; and Ido hereby declare the following description and accompanying drawings are suricient to enable any personY skilled inthc'a'rt or science 'Lto vwhich it most l nearly appertains to make and use my said invention or improvements Withoutfurthcr invention or experiment. The nature of my invention and improvements consists in providing a bell-glass or glass cylinder, closed at thetop, except an opening for a rodor supporting-standard to pass'throng'h, and having at the "bottom, on

the inside, a trough, formed by turning upthe lower edge of the glass, or otherwise, and supported by a rod or standard, with a screw cut on the upper part, and with two nuts,one within-and onewithout the glass, to adjust it to the proper height; saidA rod or standard having a broadv base extending out beneath-thetrough aforesaid, the-central part being i'omied into or provided with a cup for holding a bait to attract theyiiies. I

In the i'ollowing description, the accompanying drawings, forming part of this specification, are referred to- Figure 1 beinga plan, and i l l Figure 2 a section through the centre or the line on' tig. 1. f l The bell-glass or'cylinder A has an'opening through'thecentre of the top, through which passes the rod E, having a screw cut on the upper part, andtwo nuts, C and D, the former without and the lutter within thel glass, for adjusting it to the proper height and securing-item the'rod, the nut C serving also handle for moving' or carrying thetrap. The lower edge ofy thc glassturns up inside, and -contracts in diameter, so as to form the trough B, tohold soap-suds or other material for destroying the es. The stand-or hase, F, and braces .H H, support the rod E, andin its central part is formed vinto or provided with the cup G', for holding sugar,

molasses, or other hait to attract the flies.

The trap being placed on a. table or other surface, and the glass soadjusted in height as to leave a narrow space between the baseand the lower part of theglass, the dies, attracted bythe bait, enter beneath the-glass, l

but on attempting to leave,or.on being disturbed, they naturally ily upward and outward against the sides of the glass, attempting to escape through which, they descend into the suds and are destroyed.

1. I claim a. bell-glass or erect glass cylinder,l closed at the top, and having the lower edge turned up inside, to form a trough, as described, and-for the purpose specified. i

' 2. And in combination with tlie'bell-g-lass or cylinder described, I claim the standard, providedwith a screw and nuts, to adjustv the height of the glass.
